how can i tell by looking at the two. i read the cast crank has seams cast into it and the forged crank has no seams. how else can i tell. i know that some cast iron cranks can be 8 bolts too so that would not be a good way to know for sure

Forged cranks will have counterweights on the center main bearing journal. The cast crank lacks these.

The two in the center...

Forged cranks also typically have wide "seams" whereas cast cranks usually have narrow, pointy "seams."
